Digital audio controllers typically accept microphone, balanced or unbalanced line-level, USB, and other digital source signals, then use mixing, routing, equalization, and processing to manage audio for different zones. They can connect to amplifiers through analog outputs or networked audio protocols such as Dante, AES67, and MoIP, while control panels may link over Category cable for volume, preset, and source control.

Digital audio controllers with matrix DSP support zone-based routing and mixing, while input and output equalization helps tune audio for each space. Models with networked or wall-mounted control panels can also provide convenient volume adjustment and source selection by zone.

Plan for Ethernet cabling, with Cat 5e or better used by many controllers and linked devices for audio, control, and power, while networked systems may use Dante, AES67, or other audio-over-IP connections. Check each device’s wiring diagram for separate audio and control network connections, RS-485 requirements, RJ45 link ports, and the appropriate local or network-delivered power source.

Digital audio controllers can scale by routing multiple inputs to separate outputs, rooms, or audio zones through matrix mixing, networked audio, and configurable digital signal processing. As systems expand, integrators can connect additional mixers or processors, distribute audio over Dante or AES67 networks, and add wall-mounted control panels for local volume, source, preset, or zone control.
